A 13° slope is practically unusable. That amounts to a drop of 2¾" per foot, or a full step every 2.5 or 3 feet. On a small bathroom (since we don't have the dimensions) that could mean a drop of 1.5 to 2 feet.

You'll be replacing the whole floor, and much of the subfloor and piles, so you may as well decommission the bathroom and rip the flooring out. That'll be much easier than going into an underfloor crawl space and finding the sinkhole to hell is full of the contents of a broken sewer pipe.

Are you positive it's 13°? ... 1.3° would already be bad enough, but 13° is beginning to sound like someone just laid flooring on top of a [shallow] staircase.

I checked again and the floor is at a 2 degree slope. Sorry, no idea where I got the other number from. Apologies!

All's good :D

It's probably better to run a level over it (so the the level is ... level) and to express things in feet & inches (or meters & mm). So you end up with something like ... "my bathroom's 8'6" across, and has a fall of 2¾" ... " - because anyone that would work on your floor is going to want hard numbers, and someone's going to have to translate those degrees into inches anyway. Get rid of the unnecessary complication - it's like giving your address as a GPS coordinate and height above mean sea level instead of saying "1234 Main St, Pleasantville".
